| The pilot activates
the SVS V cable control, then adjusts
the power setting by watching the
instrument suction gauge and maintaining
level flight.
Example: If you are cruising at
full throttle at 8,000 ft., MSL,
you will have a manifold pressure
of approximately 22 inches Hg. It
will be necessary to reduce power
to approximately 18 inches Hg to
have a 4 inch differential available
to operate the aircraft instruments
after a vacuum pump failure.
In aircraft with a fixed pitch
propeller, simply observe the suction
gauge while reducing power to a
setting that will give a 4 inch
Hg reading. If you are in cruise
at 21 inches manifold pressure at
4,000 feet, you already have a differential
of nearly 5 inches Hg. If the vacuum
pump fails in this condition, simply
turn the SVS V on and you would
continue to VFR conditions or to
land the aircraft. Inflight vacuum
pump failure becomes only a minor
inconvenience - not a potential
disaster.
The SVS V is virtually maintenance
free. It weighs only 24 ounces and
can be operated even if the aircraft's
electrical system fails. Nothing
Simpler, Nothing Safer.
The SVS V is FAA approved. It is
STC'd for virtually all single-engine
aircraft. Don't wait until a vacuum
